Woohoo! There's a interesting theory (or a hypothesis) in anthropology about the beginning of linguistics, or language. I found this out when I was reading "JLA: Tower of Babel", where R'as ul Ghul decides to convolute the world's language, and instantly looked up further on the Christian mythos of that with some historical references.
Some say that "complex language", such as the predecessors of English, may have actually been invented by our species by chance. One supposition states that effect of "psychedelic fungi" that stimulated synaesthesia in some people and essentially merge sensory pathways in the brain -- essentially being able to see voices, feel sounds, smell colors, etc. which also somehow affected their survival mechanisms. Herein, our communications "expanded" beyond the primitive means and using creative means to convey ideas and experiences... with a single pen.
In other words, half the "poetic devices" most poets, writers and artists use to convey their idea comes FROM this primordial stimulus.
When you look at this bit of information AGAIN, when you read this simple post right now, at first you might just nod and go back to your daily routine lives... but inspect closely, and realize how awesome, mindblowing, miraculous even, that a "single digit" on a computer can help our brains interpret all the different thoughts that someone at the other side of the world is having in their minds right now, tinkering with different landscapes of imaginations and constructing ideas with reason, all of which can be "Transmitted" to another person with the single press of a button.
Or better yet, wirelessly, with you your "mouth" as you form sentences to a friend nearby. Every emotion, every thought that crosses your mind, every idea, every "imaginary worlds" you create that you can turn into a reality... can be accomplished with a single sentence, or a written word by using something as simple as an "ink", a blob of pigments which was "just there" until someone decided, "HOLY SHIT, I CAN USE THIS FOR... what again?"
